BIG CHANGE: REDESIGNED: Vr device simulator #1582

Browse source 
Vr simulator has been moved to core module and completely redesigned. Now user is in charge of stereo-render fbo and also in full control of distortion shader. Code is a bit more complex but better aligned with other raylib examples.
